Sciuropterus volans querceti subsp. nov. Florida Flying Squirrel. 



Ti^pe from Citronelle, Citrus Co., Fla., No. 2451, ? old adult, collection 

 of E. A. and 0. Bangs. Collected by F. L. Small, September 17, 1894. 

 Total length, 235; tail vertebrae, 95 ; hind foot, 32. 



Geogmphir, distribution. — Peninsular Florida, north to southern Georgia ; 

 exact western limits of range unknown. 



Habitat. — The hammocks and margins, where there is plenty of live 

 oak and water oak; nocturnal, spending the day in hollow stumps or in 

 nests in the thick bunches of Spanish moss. 



General characters. — Very similar to S. volans tj/picus, from which it 

 differs in having the upper parts more uniform russet, and the under 

 parts, especially the under surface of tail, strongly washed with the same 

 color ; soles naked ; audital bulUie wheel-shaped, very large and deep. 



Color.— V\-)Y>er parts russet, shading to yellowish drab in places ; cheeks 

 grayish white; upper surface of feet and hands sooty gray; toes rather 

 lighter; under parts white, a good deal shaded with pinkish russet. 

 Cranial characters.— S^nW similar to that of »S\ volans, except that the 

 audital bullae are much larger, more inflated, and 

 broadly wheel-shaped (see figs. 31 and 32). Size 

 of an average adult skull (the type) : basilar 

 lengtli, 30.2 ; occipitonasal length, 34.6 ; zygomatic 

 breadth, 21 ; greatest height of cranium above 

 palate, 12.8 ; greatest length of single half of man- 

 dible, 21.4. 



Size. — Average measurements of thi-ee adult 

 specimens from Citronelle, Fla.: total length, 

 237.G6; tail vertebnie, 102.66; hind foot, 31.33. 



General retiiarks. — Sciuropterus rolan.>< querceti 

 passes into true rolaus in southern Georgia, a 

 series of specimens from St. ]\Iarys, Ga., being in- 

 termediate between the two. A specimen from 

 Powhatan Plantation, near Gibson, La., without 

 a skull, seems referable to this form, and may thus 

 extend its range tc the coast of Louisiana. 



Specimens examined. — Total number, 3, all from 

 Citronelle, Citrus Co., Fla.
